Intrested facts about Lunar eclipse
                     What is Lunar eclipse?
A Lunar eclipse is occur when the moon is moving in the 
earth’s shadow. This can occur only when the Sun, Moon, 
and Earth are exactly or very closely aligned. 
Which Time is the lunar eclipse Start?
The total time of a lunar eclipse is determined by what is known as its 
“contacts” moment of contact with Earth’s shadow.  
●P1 (First contact): Beginning of the penumbral eclipse. Earth’s penumbra touches the 
Moon’s outer layer.
●U1 (Second contact): Beginning of the partial eclipse. Earth’s umbra touches the 
Moon’s outer layer.
●U2 (Third contact): Beginning of the total eclipse. The Moon’s surface is entirely within 
Earth’s umbra.
●Greatest eclipse: The peak stage of the total eclipse. The Moon is very closest to the 
center of Earth’s umbra.
●U3 (Fourth contact): End of the total eclipse. The Moon’s outer limb is an exit to the 
Earth’s umbra.
●U4 (Fifth contact): End of the partial eclipse. Earth’s umbra leaves the Moon’s surface.
●P4 (Sixth contact): End of the penumbral eclipse. Earth’s penumbra no longer makes 
contact with the Moon.
What is a Blood Moon?
 The first and simple meaning is related to the red color a 
totally eclipsed Moon takes on to observe on Earth. As 
sunlight from the sun is passed through the earth’s 
atmosphere the gaseous layer filter and refracts the rays 
in such a way. That the green-to-violet wavelength on the 
visible spectrum scatters is more powerful than the red 
thus giving the Moon a reddish cast is called Blood moon.
